Pushing Daisies themed wedding?

I am thinking about having a "Pushing Daisies" themed wedding. I don't want it too over-the-top, but I want subtle nods to my favorite show! I was thinking about serving different types of pie (nod to The Piemaker) and an ortment of cheeses during appetizer time (nod to Aunts Lily and Vivian), but I don't know what else. Do you have any other suggestions?
